Globalization, advancement of technologies, and increment in the demand of the customer change the way of doing business in the companies. To overcome these barriers, the six-sigma define–measure–analyze–improve–control (DMAIC) method is most popular and useful. This method helps to trim down the wastes and generating the potential ways of improvement in the process as well as service industrie...

Background: Noise pollution is one of the common physical harmful factors in many work environments. The current study aimed to assess the personal and environmental noise level and project the sound map of an Iranian tire manufacturing complex using Surfer V.14 and Noise At Work tools. Materials and Methods: This descriptive study was conducted in the curing hall [including curing, sandblast,...

The aim of an ergonomics intervention conducted in the tire manufacturing industry was to improve working conditions. Before the start, a senior manager supported the intervention. Participants were divided into teams and trained. After observing the overall performance of the teams, over 100 improvements were successfully implemented. After the improvements, there were statistically significan...

Forward integration has been explained both as a method of achieving monopoly power and as a source of greater efficiency [6, 16]. An efficiency perspective underpins the work of Chandler and Williamson who regard vertical integration, particularly into distribution, as a crucial step in the creation and success of large firms. While their views have moved closer, Chandler and Williamson emphas...

Each year, the Pacific Institute for the Mathematical Sciences organizes a one-week long Industrial Problem Solving Workshop (IPSW), where researchers from academia and industry work for five intense days to make progress on solving specific mathematical problems that arise in real industrial environments. Typically, many new, interesting mathematical results are obtained that provide concrete ...

A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...
